T all w hom it may concern Be it known that I, Fnnnnmon L. NrrsoH, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, a certain new and useful Machine for Shaping Candle Ends, of which the following is a specification.

This invention has for its object a machine for shaping the ends as the butt ends of candles, which is particularly simple and compact in construction and highly efficient, rapid and durable in use, and it consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. v

In describing this invention, reference is Yhad to the accompanying drawings in which like characters designate corresponding parte in all the views.

Figure 1 is a side elevation, partly in section, of one embodiment of my machine.

Fig. 2 is a horizontal sectional view taken on approximately the plane of line 2-j-2, Fig. 1.

Fig. 3 is an end elevation, partly in section, looking to the right in Fig. 2.

Fig. 4 is an enlarged sectional View taken on the plane of line 4-4, Fig. 2.

Fig. 5 is a cross-sectional view taken on line 5 5, Fig. 4, one of the dies and plungers being omitted.

Fig. 6 is a detail view showing in elevation the carriage for the movable jaws of the candle holding means.

Fig. 7 is an elevation of t-he butt end of the candle.

This machine for shaping candle ends comprises generally, means for engaging and holding the shank of the candle with one end as the butt end projecting, shapingl means movable into engagement with the projecting end to compress and shape the same.

The candle holding means comprises a segmental fixed jaw 1 mounted in a horizontal position on the bed 2 rising from the base, a carriage 3 and segmental jaws or die sections carried by the carriage, the carriage being movable at an angle toward and from the face of the jaw 1 to carry the jaws thereon toward and from the die or jaw 1,

have invented As here shown, the carriage 3 is provided with a fixed jaw 4 and a yielding or spring pressed jaw 5 normally extending in ad- Vance of the jaw 4 and hence when Athe candle is laid on the jaw 1 and the carriage 3 moved vertically,'the`yielding jaw 5 first engages and holds the candle and further movement of the carriage 3 compresses the springs 6 of the jaw 5 until the fixed jaw 4 engages the candle.

The carriage 3 moves in suitable upright ways 7 carried by a bracket 8 extending upwardly from the base 9 of the machine.

As here shown, the machine is adapted to operate on two candles at the same time and the jaw or die 1 is double and likewise each of the jaws 4, 5 are double.

The fixed jaws 4 are here shown as pivotally mounted between their die cavities in order to have an equalizing action as the jaws engage the candles and said jaws 4 as here illustrated are suspended by means of a link 10 having rounding ends 11, 12, the end 11 being located in a suitable bearing in the jaw 4 between the die cavities thereof and the end 12 being located in a suitable bearing in a plate 14 secured to the carriage 3 in any suitable manner as by cap screws 15, the cap screws extending through vertical slots 16 in the plate 14 in order to permit a vertical adjustment of the jaw 4 for different sizes of candles. This vertical adjustment is determined by set screws 17 threading through suitable lugs 18 on the carriage and abutting against the upper edge of the plate 14.

The end shaping means is movable with a. reciprocating carriage 19 having flanges 19Ct at its sides which move in ways formed in the frame 20 mounted on the base 9, and said means comprises tubular dies 21 supported by the carriage in axial alinement with the candle holding die sectionsl, abutments or plungers 22 movable axially of the tubular dies 21.

This shaping means also includes a tubular closure 23 encircling the die 21 and normally projecting in advance of the same toward the opposing end of the candle holding means, this tubular closure being slid; ably mounted in a guide 24 in the advance end of the carriage 19 and being pressed outwardly by springs 25 arranged in suitable passages 26 in the front end of the carriage in which passages also move tubular stems 27 provided at opposite ends lot a head 28 connecting the tubular closures, the springs 25 being interposed between the bottoms of the' passages and the bottoms of passages in the tubular stems as seen in Fig. l.

The tubular dies 21 are mounted on heads 29 arranged in the guide 24 for the tubular closures and are secured to the heads 21L of the tubular dies 21 in any suitable manner as by screws 29a.

The plungers 22 are mounted in these heads 29 and remain stationary. The carriage 19 carries the die and closures toward the candle holding means until the closure abuts against the candle holding means whereupon the carriage 19 continuing to move, moves the dies 21, axially of the tubular closures 23 and at the same time the plungers 22 are moved axially into the dies 21 to compress the projecting end 30 of the candle 31 and shape the same into the form shown in Fig. 7.

The means for actuating the movable parts of the machine comprises a main drive shaft 32 journaled in suitable bearings33, 34 mounted on the base and power transmitting mechanism between this drive shaft and the movable parts.

The power transmitting means between the drive shaft 32 and the carriage to reciprocate the same in its guide 3a comprises rock arms 35and 36 mounted on a-shaft 37 journaled in a suitable bearing carried by a bracket 38, a cam 38 mounted on the shaft 32 and coacting with a follower V39 at the end of the arm 35, and a link 46 pivoted at 41 to the arm 36 and at 42 to the carriage 3, this link being here shown as adjustable endwisely by means of a turnbuckle 43.

The cam 38 is a scroll cam and in order to hold the roller 39 engaged therewith a counterweight 44 is provided onan arm 45 also mounted on the shaft 37 and arranged on the opposite side of the shaft'37 from Ythat on which the arm 36is located.

The connection between the shaft 32 and the 'carriage 19 for the end forming dies 21 and closure 25 comprises a link or pitman 46 pivoted at 47 to the carriage and mounted at its other end on a crank pin 47 here shown as provided on one side of the cam 38. The link 48 is also provided with a suitable turnbuckle 46:L for adjusting the link thereof.

The plungers or abutments 22 are actuated relatively to the carriage and the dies 21 by means'of suitable pushers 49 mounted on the carriage 19 and coacting with sliding rods 50 which thread into the rear ends of the plungers 22. The rods 50 sliderin passages provided in a standard 51 rising from the frame and extending through an opening in the carriage 19, this carriage being mV the general form of a rectangle when viewed in top plan, see Fig. 2, the dies 21 Vbeing supported on the front side of the alunoers 22 from movement rearwardl during rearward movement of the carriage 19, friction brake means is provided consisting of a spring pressedV shoe 55 arranged in a vertical passage in the standard 51 and pressing against the flattened sides of the rods 50, the springs being inserted between the shoes 55 and blocks 56 threading into the passages in the` upright 51 in which the shoes 55 are located.

@wing to the shoes 55 the abutments or plungers 22 are held from retrograde movement during the rearward movement of the carriage 19 and the dies 21 so that the abutments act as strip-pers and reduce the strain on the candle during the rearward movement of the dies.

The means for controlling the operation of the shaft 32 comprises a clutch section 57, Fig. 2 slidably mounted on the shaft 32 and movable into and out of engagement with the complemental clutch section 58 on a drive wheel 59 on the shaft, and means for operating the clutch section 57. rthis operating` means consists of a rock shaft 60 liournzrled in suitable bearings 61 on the base 9 and having a handle 62 at the front ond of the'machine for shifting the clutch section 57 into engagement with the section 58, and mechanism for automatically shift ing the section 57 out of engagement with the section 58 at the end of each cycle of movement. l

rlhe shaft 60 operates a suitable yoke or fork 63 coacting with the clutch section 57. rlhe mechanism for automatically shifting the clutch section out of engagement with the clutch section 58 comprises aV lever 64 mounted on a shaft 60 on which the yoke 63 is mounted, see Fig. 3, and a cam point or pin 65 mounted on the periphery of awheel 66 which is mounted on the outer end of the shaft 32.

As the shaft 32 completes its rotation the pin 65 engages the outer end 67 of the lever 64 and dcpresses the same and the downward movement of the lever is transferred to the shaft 60 which rocks the yoke 63 and carries the clutch section 58 outrof engagement with the clutch section 57 The dies 21 are locked from movement Vsame and striking the bottom of the passage in which the wedge is located, the pin being yieldingly pressed in position by a spring 72 in order that it may yield whilethe wedge is being tightened by the plug 70, a plug 73 threading in the wedge against the top of the spring 72. j Y

` 1n vuse, the dies 21 may be of any suitable shape and as here shown they are formed with conical cavities formed with flutes in order to form a `conical butt on the candle and in operation, the candles are placed on the dies and pushed inwardly against the ends of the abutments or pushers 22 moving the pushers rearwardly to the limit of their movement against the resistance of the spring `pressed shoe 55.

The handle 62 is then moved kto the right (that is downwardly, F ig. 2, to shift the clutch 57 into engagement with the clutch section 58) whereupon the shaft 32 is rotated, iirst causing the cam 38 to move the carriage 3 downwardlyto carry the dies 5 and 4 successively into engagement with the shanks of the candles on the dies 1.

During this movement the crank pin 57 is moving in the upright rear arc of its orbit so that the carriage 19 for the die sections has very little forward movement. However, as soon as the candle is clamped by the die sections 4 and 5, the crank pin is moving in the lower portion of its orbit causing the lcarriage 19 to move forwardly, first carrying the closure 23 into the position shown in Fig. 4 where it abuts'against the end of the candle holding dies 1 and 5 then moving the dies 21 into the closures; compressing the butt end of the candle and shaping it. The closure prevents the escape of any of the material during the compression of the butt.

However, clearance passages 75 may be provided in the heads 29 for any excess of material. As the crank pin moves rearwardly in the upper part of its orbit the carriage 19 is moved to its starting position and as the shaft 32 completes its rotation, the pin on the wheels 66 engages the lever G4 and shifts the clutch 57 to the left, Fig. 3 out of operative position.

During the last half of the rotation of the shaft, the carriage 19 is carried to its starting position but the plungers 22 are h eld from retrograde movement by the spring pressed shoes 55 and facilitate the stripping of the dies 21 from the formed candle ends.
